How to call setUndecorated after a frame is made visible

0 votes
In my Swing application, I want the ability to switch between decorated and undecorated without recreating the entire frame. However, the API doesn't let me call setUndecorated() after the frame is made visible.

Even if i call setVisible(false), isDisplayable() still returns true. The API says the only way to make a frame not-displayable is to re-create it. However, I don't want to recreate the frame just to switch off some title bars.

How do I do this after a frame is visible?.
